Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of conveyor belt production equipment, in particular to a follow-up cutter device for conveyor belt slitting. Background Art
[0002] At present, conveyor belts are often produced with a wider width during molding, and then cut into different widths according to user needs. Figure 1 and Figure 2 As shown, during slitting, the conveyor belt 100 is pulled forward from the unwinding device 200 via the traction roller 300, and at the same time, the conveyor belt 100 is cut into strips by the cutter 400 with a fixed interval, and finally is reeled by the reeling device 500.
[0003] After being formed, the conveyor belt 100 will be more or less "S"-shaped. During slitting, the conveyor belt 100 may deviate during the traction process. This will cause the blade 400 closest to the edge of the belt to cut out of the belt.
[0004] The traditional solution is to add a correction device to the slitting machine, but the correction device has a complex structure and requires the addition of an offset sensing device and a corresponding electrical control system, which is costly. Moreover, when the sensing device detects the offset, the actual offset has already occurred. Subsequent correction can only correct the unslit part of the belt, so the correction device has a lag. Utility Model Content
[0005] The utility model aims to provide a follow-up cutter device for conveyor belt slitting, which can adjust its relative position with the conveyor belt according to the bending and deviation of the conveyor belt to prevent the blade from cutting out the belt edge.
[0006] In order to solve the above technical problems, the utility model provides a follower cutter device for conveyor belt slitting, comprising a fixed frame and a follower frame;
[0007] Two sets of belt edge slitting mechanisms are installed on the follower frame at intervals, and both sets of belt edge slitting mechanisms are equipped with side guards to position the two sides of the conveyor belt;
[0008] The follower frame is equipped with a mid-belt slitting mechanism, which cooperates with the edge-belt slitting mechanism to slit conveyor belts of various widths.
[0009] A sliding assembly is provided at the bottom of the follower frame, so that the follower frame and the belt edge slitting mechanism and the belt mid-slitting mechanism above it can move horizontally left and right on the fixed frame.
[0010] Preferably, the two groups of belt edge slitting mechanisms are movably mounted on the follower frame.
[0011] Preferably, the two groups of the belt edge slitting mechanisms are synchronously installed on the screw assembly below the follower frame, and the two groups of the belt edge slitting mechanisms are driven to move left and right under the action of the screw assembly.
[0012] Preferably, the screw assembly includes a transversely arranged screw, two sets of screw nuts and an adjustment handle at the end of the screw;
[0013] The two ends of the lead screw are installed below the follower frame through bearing seats, and two groups of lead screw nuts correspond to two groups of the edge cutting mechanisms respectively, which are connected to the lead screw.
[0014] Preferably, the thread directions of the two groups of screw nuts are opposite. When the adjusting handle drives the screw to rotate, the two groups of screw nuts drive the two groups of belt edge slitting mechanisms to move away from or closer to each other, thereby adapting to conveyor belts of different widths.
[0015] Preferably, the sliding assembly includes a slider and a slide rail, the slide rail extends in the left and right directions on the fixed frame, and the slider is connected to the follower frame, thereby driving the follower frame and the belt edge slitting mechanism above it and the belt mid-slitting mechanism to move horizontally left and right along the slide rail.
[0016] Preferably, the belt edge slitting mechanism includes a belt edge knife holder for clamping the belt edge cutter; and also includes a side guard for positioning the side edge of the conveyor belt.
[0017] Preferably, the belt slitting mechanism includes at least one group of belt knife seats for clamping the belt cutter; the belt knife seats are slidably installed on a transversely extending circular shaft, so that the belt knife seats drive the belt cutter to move horizontally left and right along the circular shaft, thereby cutting out conveyor belts of various widths.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] During the conveyor belt slitting process, the ribs of the belt edge slitting mechanisms on the left and right sides of the follower cutter device position the conveyor belt body. When the belt body bends or deviates, the lateral force of the belt body on the ribs is transmitted to the follower frame through the screw assembly, pushing the follower frame to move to the bent or deviated side. The belt edge slitting mechanism and the belt mid-slitting mechanism fixed on the follower frame also move in real time, thereby realizing the follow-up of the slitting blade with the conveyor belt body during slitting.

[0033] Specifically, the two groups of the belt edge slitting mechanisms 3 are movably installed on the follower frame 2, and the two groups of the belt edge slitting mechanisms 3 are synchronously installed on the screw assembly 6 below the follower frame 2, and are driven by the screw assembly 6 to move horizontally left and right.
[0034] Furthermore, the screw assembly 6 includes a transversely arranged screw, two sets of screw nuts and an adjustment handle at the end of the screw; both ends of the screw are installed under the follower frame 2 through a bearing seat, and the two sets of screw nuts correspond to the two sets of the edge cutting mechanisms 3, respectively, connecting them to the screw.
[0035] In one embodiment, the thread directions of the two groups of screw nuts are opposite. When the adjusting handle drives the screw to rotate, the two groups of screw nuts drive the two groups of belt edge slitting mechanisms 3 to move away from or closer to each other, thereby adapting to conveyor belts 100 of different widths.
[0036] Specifically, the sliding assembly 5 includes a slider and a slide rail. The slide rail extends in the left and right directions on the fixed frame 1, and the slider is connected to the follower frame 2, thereby driving the follower frame 2 and the belt edge slitting mechanism 3 and the belt mid-slitting mechanism 4 above it to move horizontally left and right along the slide rail.

[0039] During the slitting process of the conveyor belt 100, the side ribs 303 of the belt edge slitting mechanisms 3 on the left and right sides of the conveyor belt are used to position the conveyor belt body. When the belt body bends or deviates, the lateral force of the belt body on the side ribs 303 is transmitted to the follower frame 2 through the screw assembly 6, pushing the follower frame 2 to move toward the bent or deviated side. The belt edge slitting mechanism 3 and the belt mid-slitting mechanism 4 fixed on the follower frame 2 also move in real time, thereby realizing the follow-up of the slitting blade with the conveyor belt body during slitting.
